` TORCH.

Application filed January 31, 1911. v Serial No. 605,741.

To all whom t may concern Be it known that I, HAELoN A. CLIFFORD, acitizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented a new and useful Torch, of which the following is a specification. l The device forming the subject matter of this application is a torch adapted to be employed for applying a mixture of oxygen and gaseous fuel to a material, 'for the pur pose of welding and .for cutting the same.

The invention aims to provide a torch of this character in which the angle between the burner and the handle may be changed without interfering with the flow of fluid through the handle and to the burner. A further object-of the invention is to provide novel means for securing a thorough mixture of gaseous fuel and oxygen 'in the mixing chamber of the burner.

The invention is designed, moreover, to provide a torch having separable cutting and welding elements, each provided with an individual fluid supply.

Another object of the invention is to provide means for preventing a flash-back of the ignited fluids.

Novel means are supplied for assembling 'the various elements of the torch in operative relation to one another.

With the foregoing and other objects in View which will ,appear as the description proceeds, the invention vresides in the combination and arrangement of parts and in the details ofconstruction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made with in the scope-of what is claimed withoutdeparting from the spirit of the invention.

E-F of Fig. 1; Fig. 7 is a section on the line G-H of Fig. 1; Fig. 8 is a detail perspective view ofthe plug which is inserted into the mixingchamber of the burner `for the purpose of securing a thorough mixture of gaseous fuel and oxygen; and Fig. 9 is a section through a modified form of primary nozzle, the cutting plane passing through such modified structure in approximately the same place as that in which. the plane G-H passes through the structure shown in Fig. 1.

The torch herein disclosed comprises three fundamentalparts; handle, a burner- Isupport and a burner. The handle and the burner-support are pivotally united so that the angularrelation between them may be altered; and the burner is detachably secured to the burner-support. These fundamental parts will be described in order.

'The Mantua-The handle is a composite structure and includes a tubular casing 1,`

provided at one end with a base 2, and at the other end with a cap 16.- Located within the casing 1 is a tube 9 of less dialneter than thecasing. The tube 9 extends `from the base 2 to the cap 16, the ends of the tube being supplied with wire gauze closures 10, retaining in place within the tube a packing 11 of asbestos or the like. A. gas supply pipe 6, controlledby a valve 3, enters the base 2 and `communicates with the interior of the tube 9. Oxygen pipes 7 and 8 enter the-base 2, the pipe 7 being coni trolled by a valve 4 and the pipe 8 being controlled by a Valve 5. lAs shown at 12 the4 torch. lThe pipe 7, as shown at 14, passesl through the casing 1 and enters the head 19. Communication is` established between the .tube 9 and the head 19 by means of a p ipe 17, united with the cap 16 by a connection 18. The parts 12 and 14 of the pipes 8 and 7 respectively, are packed with asbestos, as shown at 15. The packings 11 and 15 serve to prevent a flash-back of the ignited fluids which the pipes 6, 7 and 8 conduct. In one of lthe side faces of the vhead'l9 there are concentric annular grooves 20, 22and 24. A duct 21 in the head 19 serves to establish communication between the pipe 17 and the groove 2.0, another duc't 23 connecting the Apipe 7 with the Agroove 22, and a thirdpductl of the burner-support 26 there are concentric annular grooves, registering respectively 'with the grooves 20, 22 and 24 of the head 19. A pivot element 27 connects the burner-supe port 26 with the head portion 19 ofY the handle, so that the burner-support and' the handle may assume different relative angles. Owing to the fact that the' grooves 20, 22 and 24 of the head are concentric with the corresponding grooves in the burner-support, the fluid conduits through the handle and the burner-support will remain continuous when the burner-support is swung about upon its pivotal connection 27 with the head 19.

In the uter end face of the burner-support 26 there., is an annular groove 29 concentric with another annular groove 32,' of smaller diameter than the groove 29. A passage 28 inthe burner-support 26 seives to establish communication between the groove 29 upon the one'hand, and the groove 24 in the head 19 and the registering groove in the burner-support 26 upon the other hand. A passage 31 in the burner-support 26 serves to establish communication between the groove 32 upon the one hand, and the groove 22 in the head 19 and the registering groove in the burner-support 26 upon the other hand. There is a third passage 30 in the burnerLsupport 26, this passage opening at i' one end yinto the groove 20 in the head 19 and into the registering groove in the burner-support 26, and at the other end opening through the end wall of the burnersupport at the center of the grooves 29 and 32.

ThevburneoxThe burner includes a prilnary nozzle 35 having at one end a lateral.

flange 34 abutting against the end wall of the burner-support 26. The primary nozzle 35 is removably held upon the burner-support 26 by a collar 36, overlapping the outer face of the flange 34 and threaded upon the burner-support 26. The bore 42 of the pri-v mary nozzle 35 is enlarged within the flange 34 of the primary nozzle to form a mixing chamber 43. In the mixing chamber 43 is located a plug 40 having an axial passage 41 communicating at one end with the forward portion of the mixing chamber 43, and atthe. other end communicating with the passage 30 in the burner-support 26.v In the side wall of the plug 40 there are diagbnal grooves 44 communicating at their rear ends with the annular groove 32 in the outer end` face of the burnersupport 26, and at their forward ends opening into the forward porprising a tube 38 seated in a longitudinal 70 groove 47 in the4 side face of the rimary nozzle 35, the tube 38 being removably connected with the flange 34 of the primary nozzle 35. The tube 38 of the secondary nozzle carries a removable cutting tip 39,

having a reduced bore communicating with the bore of the tube 38. vThe bore of the tube 38 opens into a passage 37 through the flange 34 of the primary nozzle 35, the passage 37 opening into an annular groove 33@ 80 in the rear face of the flange 34, 'the groove 33 registering with the groovel 29 in the outer end face of the burner-support 26. The registering grooves 29 and 33, and the groove 32, may contain a packing of 85 asbestos and metallic gauze, for the purpose of preventing' a flash-back of the ignited fluids.

0pemtz'on..-Presupposing that the con trolling valves 3, 4 and 5 Vare open, the gas 90 which is to be burned will enter the pipe 6 and pass thence through the tube 9 to the pipe 17 and by way of the duct 21 into the annular groove 20, and by way of the passage 30 in the burner-support 26, to the cen- 95 tral passage 41 in theplug 40, and into the mixing chamber 43 in frontof the plug 40. From the mixing chamber 43, the gas will pass through the bore 42 of the primary nozzle 35, to the extremity of the primary 100 nozzle, at which point the gas will be ignited. The oxygen entering the pipe 7, will pass through the casing '1 and traverse the duct 23 to enter the groove 22. From the groove 22 the oxygenwill traverse the passage 31 105 and enter the groove 32, passing thence by way of the inclinedgrodves 44 in the side face of the plug 40 into the mixing chamber 43, and thence with the gas which is simultaneously delivered into the mixing chamber, through thebore 42 of the primary nozzle 35. Owing to the positions of the grooves 44 in the side walls of the plug 40 and owing to the fact that these grooves eX- tend acrossv the end face of the plug as' shown 115 at 45, the oxygen will be .given as iral mo tion as it enters the vmixing cham er '43, a thorough admixture of gas and oxygen being thereby effected. The path traversed by the oxygen supplied to the cutting tip 120 39 is as follows; the pipe 8, the duct 25, the annular groove 24 in the head 19 and its fellow in the burner-support 26, the passage 28, the registering annular grooves 29 and 33 in the burner-support 26 and inthe 125 flange 34 of the primary nozzle 35 respectively, the passage 37 through the flange 34, the bore of4 the tube 38 of the secondary nozzle, and out through the bore of the cut- 'iso ting tip 39 of the secondary nozzle.

When the torch is to be used for-welding, the secondary nozzle. 38-39 may be removed, the valve being closed. When the torch is to be used for'cutting purposes, the

secondarynozzle 38-39 will remain in place as shown in Fig. 1. The longitudinal grooving of the primary nozzle 35 atv47. to receive' the tube 38 ofl the secondarynozzle, serves.

to hold the ignition ends of the twonozzle portions of the burner assembled for opera-f i axial bore 42, corresponding to the lio're 42.

of' the nozzle 35. `About the bore 42l are disposed supplemental bores 46. y All of the bores 42 and 46 arefor a single purpose,:to

wit, to serve as conduits which carry a.m1 X-, 4vture of .gas andy oxygen Afrom the 'mlxlngchamber 43 to the outer end. of the primary nozzle 35', this mixturefof gas and oxygen passing,'in the structure shown' in Fig. l,

through the s1 nozzle 35.
